Description
General part information
TPA6040A4 Series
The TPA6040A4 is a stereo audio power amplifier and DirectPath™ headphone amplifier in a thermally enhanced, space-saving, 32-pin QFN package. The speaker amplifier is capable of driving 2 W per channel continuously into 4-loads at 5 V. The headphone amplifier achieves a minimum of 85 mW at 1% THD+N from a 5-V supply. A built-in internal 4-step gain control for the speaker amplifier and a fixed -1.5 V/V gain for the headphone amplifier minimizes external components needed.
Independent shutdown control and dedicated inputs for the speaker and headphone allow the TPA6040A4 to simultaneously drive both headphones and internal speakers. Differential inputs to the speaker amplifiers offer superior power-supply and common-mode noise rejection.
